The melanocortin 1 receptor (MC1R) gene was investigated as a candidate for plumage variations in Chinese painted quail, Coturnix chinensis. Four silent and two missense nucleotide polymorphisms were identified. The correspondent amino acid changes, p.Glu92Lys and p.Pro292Leu, were found in Blue Face and Red Breasted animals respectively. Blue Face is a melanic phenotype similar to the co-dominant Extended Brown of Japanese quail, and both share the p.Glu92Lys mutation. The association of p.Pro292Leu with the recessive Red Breasted was confirmed in 23 animals from an experimental F2 cross.
研究了黑皮质素1受体（MC1R）基因作为中华鹌鹑（Coturnix chinensis）羽色变异候选基因的可能性。鉴定出四个沉默核苷酸多态性和两个错义核苷酸多态性。分别在蓝脸和红胸鹌鹑中发现了相应的氨基酸变化，即p.Glu92Lys和p.Pro292Leu。蓝脸是一种黑化表型，类似于日本鹌鹑的共显性扩展棕色表型，两者都有p.Glu92Lys突变。在一个实验性F2杂交的23只鹌鹑中，证实了p.Pro292Leu与隐性红胸表型的关联。
